The subjects were elementary school pupils and undergraduates (N = 158) in two cultural selections under two conditions of measurement of the impact of a socio-psychological training (SPT) in Slovakia and Denmark. Using the method for measuring uncertainty-certainty (Kovac, 1969) we found that after SPT there followed a significant decline of uncertainty in all the types measured (normal, increased and pathological uncertainty). A significant increase in certainty was noted following SPT in the subscale normal certainty in all the subjects of the Slovak sample, while the shift toward enhanced certainty in the Danish sample remained nonsignificant. Measurement after a lapse of one year since the SPT in the Slovak children pointed to a stabilization of the SPT impact in the subscale normal certainty toward higher certainty.
